Surface Property Dependent Biocompatibility Analysis of NiTi Shape Memory Alloys to be used in Root Canal Shaping Applications
Journal Title: International Journal of Dentistry and Oral Science (IJDOS) - Year 2018, Vol 0, Issue 2
Abstract
Aim: The current study aimed to evaluate the biocompatibility of NiTi SMAs, to be used as root canal shaping instrument materials, in relation to their surface properties. Material and Methods: NiTi SMA samples with different surface properties were subjected to ex situ and in vitro biocompatibility tests following their initial structural analysis via SEM and profilometer. For the ex situ tests, the samples were statically immersed in AS for 24 hours and their surfaces were examined via SEM. For the in vitro analysis, fibroblast cells were seeded on the samples for 24 hours, which were then fixated on the sample surfaces and examined with SEM in terms of their attachment behavior and morphologies. The numbers of viable cells on each sample were also counted with Cellometer. Results: The NiTi SMA sample with lower roughness values exhibited better biocompatibility in both ex situ and in vitro tests with lower corrosion product deposition and increased cell viability. Conclusion: Among the tested samples, the NiTi SMA sample with lower surface roughness constitutes a better alternative as a root canal shaping instrument material
